The court said the first exception to section 499 of the IPC (defamation) requires to be seen whether the imputation is for public good and added that exposing corruption "certainly" falls under that category.
It said there may be cases where the expose is made with ulterior motives but it needs to be proved by the complainant.
"Exposing corruption of the government department is certainly for public good. It is the duty of every responsible citizen to expose corruption.
"There may be certain cases where an individual or any other body of individual or corporate body exposes corruption for seeking revenge or for ulterior motives. In such cases the ulterior motives have to be proved by the complainant," said Metropolitan Magistrate Rajinder Singh.
The court's order came on a defamation case filed by a former Indian Institute of Public Administration professor, seeking prosecution of the editors of Jan Vikas, a Delhi-based weekly, for publishing a news 'No action by municipality despite court orders'.
The complainant told the court that the "libellous" news naming him was published in December 2007. The article was about "unauthorised constructions" in South Extension-I, a posh south Delhi locality, he said. (More)
